F350

The unique V8 power solution for larger boats

Created for the heavy-duty demands of large offshore boats, the 5.3 litre Yamaha F350 is a mighty technological pioneer. This 4-stroke V8 is the world's largest displacement outboard, combining unique levels of power and torque with the refined performance required by today's sophisticated hull designs.

Yamaha's EFI (Electronic Fuel Injection) delivers smooth performance and maximum fuel efficiency across the power band - and despite its size and power, Yamaha's weight-saving technologies have made the F350 surprisingly light and compact too.

With the PrimeStart™ system, starting is as easy as in your car - and digital drive-by-wire technology keeps you in precise control.
